I fpplicaton filed August 1, 1925. Serial No.,47,43'2.

This invention relates to locks of the' pin tumbler type and moreparticularly to' the manner in which the pi tumbler barrel and'associated l mechanismv is connected to the lock casing.

- accomplished.

vThe Vprincipal objrect of the invention is" the production of simpleand' novel means by lmeans ofr Which the usual bolts or screws' forconnecting the pin-tumbler barrel to the loclcasing may be threadedthrough the usual earson the tumbler barrel before they are insertedthrough thev usual openingsin the. rear plate ofi the l'oclr) lcasingthereby making. it unnecessary to .feel`' for' the ears ascust'omaril'y.v

further object of the invention is the produetion with thejrear or coverplate of they lock casingy frfa supplemental movableoi' slidabl'e platelor plates by means of which V theprinkcipal object ofthe invention' maybeV f 4 ln" the laccomp'anyng drawing illustrating a practicalembodiment ofthe invention: y

Jhon the pai-ts have been assembled andthe piirtiiinbler barrel hasl been inserted in the opening it has beencustomary to hold the plate` 6 against the rear it'ace of the door withthe operating spindle i3 extending through the oiieiiing 1l. and theninsert the screws or bolts through their openings and thread themthrough the ears il until the plate G is 'tigihtly clamped against thedoor. This has made it necessary to t'eel .tor the ears Qiwitli the endsolf the screws or bolts l5 which has been an awkward and therefore anobje@ tionable operation. lly ineens of this inveution this objectionhas been overcome as the screws or bolts 15 are iii'st thi' aided partially through the ears 9. The pin tumbler barrel is then held in theopening T as ordinarily and the rear plate (i with the supplementalplates 'i9 in open position is held againstthe inner tace oit the doorwith the operating spindle l2 extending through the opening 11i and withthe heads et the screws 15 extending through theimenings 14E. It isimmaterial il? the operating spindle 13 should sag slightlyas the slots12 have been provided to receive said spindle should this conditionobtain. litter the parts described have been properly positioned theplates 1S) are brought into .meeting engagement with thelocling lugs Q5enteringr the slots 2l. The screws 15 are then screwed cheine with theheads thereof engaging the beveled edges of the round openings termed bythe semi-circular openings but as said open ings are too small toreceive the heads oi said screws therethrough the parts are all heldtightly in assembled and operatiye po? sition. The lock easing' 5 isthen screued to the door with the rear plate G entering said casing inlthe usual manner.
